3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 1dc56c52d2484be09c7398a5207d6b11a4256be9 upstream.
Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer should the probed device lack endpoints.
Note that this driver does not bind to any devices by default.
Fixes: ce21bfe603b3 ("USB: Add LVS Test device driver")
